UNITED STATES STEPHEN S. NEWTON, OF BINGHAMTON, NEW YORK.

CHANDELIER.

SPECIFICATION forming part of Letters Patent No. 257,054, dated April 25, 1882.

Application file'd December 27, 1881. (No model.)

To all whom it may concern Beit known that I, STEPHEN S. NEWTON, a citizen of the United States of America, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Chandeliers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make.and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Heretofore it has been customary to construct locks for chandeliers having telescoping tribe-sections in'such manner that one part of the lock is crowded against one or the other of the tubes. The tubes employed for this purpose are generally made thin and light, and therefore they are not adapted to receive much strain or pressure. Hence the common construction is disadvantageous, in that it forces one of the locking-pieces against one or the other of the tubes.

' The object of my present invention is to combine with the stationary tube and a sliding chandelier-tubeastrengtheningpartforthe stationary tube and locking devices, so arranged that in whatever position the chandelier may be they shall bear against the said strengtheniug device when operating to lock the chaudelier.

Figure l is a vertical section of a chandelier Figs. 2, 3, and 7 are similar sections of modified forms. Fig. 4. is a cross-section on line a; :20, Fig. 1. Fig. 5 is a cross-section on the line 3 1 Fig. 3. Fig. 6 is a cross-section of a form slightly different from that in Fig. 1.

In the drawings, A represents the upper stationary tube-section, having at the upper end a bulb or shell, B. in this bulb is a frame, a, carrying a swivel-eye, a, a spring-drum, O, and a guiding-pulley, 0, there being a cord, G, attached to the drum (3 and extendin gdownward. The frame a is preferably connected to the upper tube, A, by a threaded connection. In the lower end of the stationary tube-section Athere is a strengthening collar or annulus, D. Preferably it is made as shown, it consisting of a brackets G. Across the interior of the bulb F is a cross-piece, H, provided with a slot at h. pivoted at t within the shell, and having a projecting catch-piece, i.

J represents a locking-bar. At the upper end it is attached to a guiding-plate, d, which fits within and slides in the upper stationary tube-section, A. The locking-bar is attached to the guiding-plate by means of a pivot, upon which it swings when moving out and in. At the lower end the locking-bar J passes through the slot 71. in cross-barH, there being a loose connection between them at that point either by a pivot or by pins h. This bar J is provided with inclined'or wedge-shaped faces J. Opposite to this bar J there is another lookin g-bar, K, having similar inclined or wedgeshaped faces, K. The second locking-bar, K, is at the upper end connected to the cord (3 and at the lower end is attached to the thumblever I, being slotted to receive a pin passing through said lever. That portion of the bar J which passes through the cross-piece H prevents theouter tube from rotatingrelatively to the upper one. The locking-bars J and K pass through a square or oblong aperture in the strengthening-piece D, so that they are always held in proper working position. It will now be seen that the weight of the chandelier will tend to force apart the two locking-bars J and K,which forcin g of these bars compels them to press tightly against the part D, and the resulting friction operates to firmlyhold the chandelier. When it is desired to unlock the tubes the chandelier is pushed up a little and the thumb-lever I is pulled downward, which at once draws the locking-bar's toward the center of the tube and stops the frictional engagement with the part D. It will, moreover, be

Below this is mounted the thumb-lever I,

seen that in whatever position the chandelier and its sliding tube-sectionE may be the looking will always beagainst the strengthening collar or disk D. This part therefore receives allof the serious strain and wear, and by the use of it I obviate entirely the breaking or bending of the stationary tube-section which is incident to the chandeliers employing frictionstops as now made. Hence 1 can employ much thinner tubes and can greatly cheapen the construction of the chandeliers.

Instead of the wedging-faces J and K for crowding the locking-bars against the part 1), use may be made of links, such as shown atL in Fig. 2, which will operate in a manner substantially similar to said wedges. In some respects these links are preferable, as the bars J and K can be cast in simpler form and with less metal when the links are to be used. Fig. 2 also illustrates the fact that one of the bars, asJ, may be permanently fastened in positionas, for instance, to one side of the shell or bulb F-leaving the other bar, as K, to be thrust outward against the piece D.

Instead of having the, thumb-lever I arranged eccentrically, as in Fig. 1., it may be arranged centrally, as shown in Fig. 2, a supplemental link, 1, being used, if necessary, to connect it with the swinging locking-bar.

The locking-bars J and K may be arranged to be forced outward by a wedge, as shown in Fig. 3, both bars in this case preferably being free at the lower ends to swing out. and in to a limited extent, the ends being confined within the slot h in cross-piece H.

M represents a wedge, which, as shown, is attached to the thumb-lever I at the lower end and at the upper end is connected to the cord 0, running down from the drum (J. The weight of the chandelierand the connection of the spring-drum C in this case tend to draw the wedge between the locking-bars J and K and force them out against the piece D to clamp the chandelier in any desired position.

When a construction like that in Fig. l is used the parts J and K may be made semicircular in cross-section instead of square, and yet be prevented from rotating in the tube by using afeather or spur, N, fitting in a curve or recess in one or both of the parts, as shown in Fig. 6.

In Fig. 7 I have shown a modified form employing two wedges, one situated near the bottom and the other near the top of the lower tube section. In this construction the swing ing parts J and K are preferably in the form of sections of tube, having at the lower end opposing fiaring faces or shoulders at m and at the upper end similar shoulders or faces, 112. With these engage the two conical wedges at M and M, such engagement operating to force the parts J and K outward to lock the tubes. The wedges M and M are connected together by'an intermediate rod or cord, and are connected to the cord O by an eye. The thumbpiece I extends directly from the lower wedge,

M, through the bottom of the shell. locking device of this sort the parts J and K .are crowded outwardly not only at the lower end, but throughout their whole extent, thus producing an engagement over a greater surface. I do not, however, dispense with the strengthening-collar D, but use it either inside the stationary tube, as in said construction, or outside of the tube around its lower end, as shown in Fig. 7. hen outside it 0perates in substantially the same manner to prevent the cracking, wearing, or straining of the tube at the lower end.

The lower end of the bar J may be utilized to prevent the tubes A and E from rotating relatively to each other, either by the flattened portion passing through the cross-bar E in the shell F, as in Figs. 1, 3, and 7, or by securing it rigidly to the shell, as shown in Fig. 2, this bar in both cases being so shaped relatively to the aperture through the part D as to prevent any rotary movements of either relatively to the other. e

I am aware that chandeliers have been heretofore constructed with a stationary tube-section, a sliding tube-section, and means for preventing the sections from rotating relatively to. each other, and I do not claim broadly such devices as my invention.

What I claim is-- 1. In a chandelier, the combination, substantially'as herein set forth, of the following elements, namely: an upper stationary tube, a lower sliding tube, the strengthening-collar D, adapted to receive the pressure of the looking devices, the locking-bars J and K, and devices, substantially such as described, to crowd said parts J and K against the strengthening part 1).

2. The combination of the lower sliding tube, the upper stationary tube, the strengthening.- collarD at thelower end of said stationary tube, the bar K, adapted to be thrustoutward against the strengthening part D, and the bar J, passing through said part D and connected to the lower shell, F, substantially as described, whereby it prevents rotation of the lower tube relatively to the other.

3. The combination of the lower sliding tube section, the upper stationary tube, the strengthening-collar D at the lower end of the upper tube, the frictionbars J K, extending from the upper end of the sliding tube to the lower end,

and mechanism, substantially as described, for forcing said bars outward against the part D, as set forth.

4. The combination of the lower sliding sec tion,the upper stationary section,the twolocking-bars J K, extending from the upper end to the lower end of the sliding tube-section, and a wedge having inclined faces separate from the locking-bars and operated by the weight of the chandelier to throw said bars outward to lock the sliding section, substantially as set By a ments, viz: the lower sliding tube-section, the upper stationary tube-section, a cord winding mechanism attached to the upper tube-section, a locking-bar carried by the lower tube-section and extending from the top to thebottom thereof, a sliding supportin g-piece, d, at or near the upper end of the lower tube-section, to which the upper end of thelockin g-bar is pivoted, and devices,substantiall y as describcd,which throw said locking-bar outward upon the pivot in said plate to lock the sliding section, as set forth.
